DS1035Z-15 Application Field and Working Principle

The DS1035Z-15 is a low cost, high-performance delay line with a programmable delay range up to 15ns (nanoseconds). The delay line belongs to the category of Clock/Timing – Delay Lines. It is used to provide clock data signal retiming and signal path delay matching in a variety of communications, control, and signal integrity applications. This article will provide general information regarding the working principle and application field of the device.

The DS1035Z-15 is an advanced delay line designed to provide precise signal delays with low jitter and power dissipation, as well as a low cost signal buffering capability in a very small package. It is equipped with advanced signal conditioning circuitry, high-impedance drive capabilities, and an integrated high-frequency signal splitter. This enables the device to perform precise signal delays with low power dissipation and signal paths free of distortion. The delay line can also be used to improve signal integrity and reduce delay line loss by providing more uniform signal timing.

The DS1035Z-15 is specified to provide precise delay times with ±1% accuracy for signal path delays of up to 15ns. It has a high dynamic range of up to 80dB, and a low propagation delay of 0.12ns compared to other industry-leading devices. The device also has an integrated power-on reset feature to ensure accurate signal retiming after power-up.

In terms of its operational parameters, the DS1035Z-15 offers input rise/fall time of less than 1.5ns, output enable (OE) pulse width of 25ns and output disable (OD) pulse width of 8ns. It also features a -3dB bandwidth of 1.4GHz for maximum signal integrity, and power management capabilities to provide low power operation.

The DS1035Z-15 is flexible in terms of its applications, with its programmable range of delays of up to 15ns allowing for optimized signal path matching and retiming in many different environments. It can be used for clock data recovery and signal path delays in telecommunications, data communications, data storage, and high-speed serial communication systems. It is also suitable for retiming of signals in high-clearing applications in industrial automation and control, industrial instrumentation, and medical instrumentation.

In terms of its working principle, the DS1035Z-15 is a delay line that consists of a high-speed clock driver followed by a bank of cascade delay stages. The high-speed clock driver is used to set the delay, with the number of stages adjusted according to the required delay time. The delay stages consist of a series of D flip-flops, whose outputs are connected to the DS1035Z-15\'s data output pin. The delay stating of each stage is programmed with the clock driver. As the clock’s frequency is increased, the amount of delay produced by the delay stages is reduced and the resulting signal is outputted from the DS1035Z-15\'s data output pin.

The DS1035Z-15 also offers an integrated, high-frequency splitter to provide low jitter and low-impedance buffering for improved signal integrity. The splitter can be configured to split a single input into two or four separate outputs. This allows the device to be used as a two- or four-way repeater, providing buffered signal paths which can be used to generally increase system speed or to provide improved signal integrity.

In summary, the DS1035Z-15 is a low cost, high-performance delay line manufactured by Texas Instruments. It belongs to the Clock/Timing – Delay Lines category and is used to provide clock data signal retiming and signal path delay matching in a variety of communication, control, and signal integrity applications. It offers a high dynamic range and low jitter, as well as the option of a two- or four-way repeater for improved signal integrity. The delay line is specified to provide a programmable delay range of up to 15ns with ±1% accuracy, and it operates with a low power dissipation and input/output delay times of less than 1.5/25ns. All these features make the DS1035Z-15 an ideal solution for many application fields.
